These functions use low-level fileio to write any set of files to
diskette. Their main advantage, over simple copying is that they can
split files across 2 or more diskettes. It is 100% Clipper and all
needed source is included here, including a demo calling routine. The
coding style is a little old fashioned, with mostly private variables
being used. I have replaced a few, but not disturbed most due to the
original author's use of macro compilation and memory files. Besides,
if it works, don't fix it. I did add 5.3 pushbuttons, though.

Their main weakness, compared to a commercial product such as
ProVision Backup, which I now use instead, is that this routine does
not format diskettes on the fly and does not use any compression. In
addition the estimated time display is wildly inaccurate, owing to the
substantial speed differences in disk read/write times on the array of
modern PCs out there. At the time this was written, most everything
was still a slow '386, at best. You may wish to adjust the value used
on line 324 downward or upward, depending up the target platform. On
my Pentium 90 2900 bytes per second is about a fourth of what the
computer is doing, or less.

the main program runs.

Events are evaluated in idle-time, when Clipper is waiting for a key,
like inkey().

every day of the year in 46 bytes (1=.T., 0=.F., 366 days /
8 bits = 46 bytes).

that it can handle reading from more than one file at a time by
saving the specifics in arrays in the calling function.

If you are only operating on one text file at a time, BUFFREAD is
easier to use, since it requires no extra variables to be created.

CauseWay Tools Package 1 Version 1.0 Documentation
==================================================

The CauseWay Tools Package 1 contains three useful routines for
programmers using the CauseWay for Clipper 5 package, including
commented assembly language source. Although they are generally
self-documenting (standard weasel words to avoid having to create a
large READ.ME file), following is a short overview of what is
provided. But first, the generic legal blurboid:

All SOURCE CODE contained in CauseWay Tools Package 1, consisting of
the files FILEVIEW.ASM, GETENV.ASM, and SETENV2.ASM, is hereby
released to public domain. Michael Devore grants no warranties,
express or implied, regarding the CauseWay Tools Package 1's fitness
for any application, use, or purpose. Use of these routines is
strictly at your own risk and pleasure.

The showcase of CauseWay Tools Package 1 is the 100% assembly language
file viewer, written by Ted Means. This nifty utility allows viewing
ASCII files up to 4G in size via a Clipper-callable routine. You can
control many of the display aspects of the file viewed, via keystrokes
or other mechanisms.

A small example PRG, called CWFVDEMO.PRG that demonstrates use of the
file viewer is included. Simply compile it with Clipper's /n option
and then pass the file name you wish to view on the command line.

SETENV2.ASM is a version of the public domain SETENV.ASM by Kevin
Saffer modified by Michael Devore to work in protected mode. SETE
will add variables to the DOS master environment table.

GETENV.ASM is a small routine written by Michael Devore which behaves
the same as Clipper's internal GETENV routine. This version, however,
does not fail, disapprove, or act inappropriately if an environment
variable, such as PATH, exceeds 127 characters.

Note that linking in GETENV.OBJ probably will cause a duplicate symbol
warning because the Clipper module which defines GETENV also defines
GETE, meaning that the module still gets linked in. If you find this
particularly bothersome, you can modify GETENV.ASM to publicly list
GETE as an additional entry point (currently that's all Clipper does
anyway, force GETE to call GETENV).

Any questions, comments, bug reports, or feature enhancements, please
direct them to Michael Devore [71540,62]. He will forward on any file
viewer comments more appropriate for Ted's examination.

A small collection of Clipper '87 routines to allow you to download
soft fonts to your LaserJet + or II (or compatible) from within
Clipper. ( should be 5.x compatable )

By Mark Leavitt MD PhD, MedicaLogic, Inc., Compuserve 73270,672
Placed in the public domain...use and enjoy!
Thanks to Brad Codd who provided BINMODE which inspired IOCTL routines

Background: The HP LaserJet + and II, and compatible laser printers,
accept "soft fonts" which can be downloaded into the printer's memory.
The soft fonts are supplied as disk files. Because these files are
essentially binary, and can contain characters such as ASCII 0 (null),
ASCII 26 (eof), the recommended method for downloading has been to use
the DOS command:

COPY /B FONTFILE.HPF LPT1

(The /B causes a binary copy which ignores end-of-file characters.)

Clipper programmers hate to use DOS because of memory limitations with
the RUN command, possible cryptic DOS error messages, and such.
Attempts to download fonts using SET PRINTER TO, SET PRINT ON are
doomed as the DOS printer driver intercepts end-of-file characters.
The trick here is to place the printer driver in binary mode (called
"raw" mode) instead of character mode ("cooked" mode) using an obscure
MS-DOS call called IOCTL. That is the purpose of the assembly language
module supplied here.

FastClass by: szguoxz@public.szptt.net.cn

This product is based on ooclip15, so if you can't find some
introduction of this product, you refer to ooclip15.zip in oasis site.

FastClass supports Debug. I have found how to support Debug, but I
don't think it's neccessary, So if you're interesting in it, contact
me, I can tell you how to modify the send.asm of clipper to make it.

FastClass supports Super message. I found if I support the supper
message, such as ::super:init, the execute speed of class will much
more slow than FastClass, so I didn't include it in my product. If
you're interesting, contact me.

As to the speed, FastClass uses the fastest way for CLASS PROGRAMM
under clipper structure, while ooclip also. Because Classy and Objec1a
both use Code Block as method, so its speed must be slower than Fast
Class and OOCLIP.

(Note: In fact,Classy did some trick on that method, so it's a little
faster than Objec1A, but since it supports SUPER message, and other
complicate feature of CLASS PROGRAMM, it's speed is even slower.)

As to the size of FastClass, it's the smallest one. It modified the
send.asm of clipper, so it won't add anything to your exe file, except
a class making function, and some programm supporting clipper valtype
variables as class, which are wroten in prg.

Support Clipper Variables as Class
You can see:

x := date()
? x:size

You'll get 8.

You can add your own features for every clipper valtype bu modify the
ooclip.prg.

You can get the address of functions(include static functions). This
is only available in Fastclass.

For example:

x := GETADDRESS( work )

then, at anywhere else in your programm, you can use:
x:eval()
to execute the function work.

Many new programmers may wonder how a function was put together in a

So What's special about this ... well to be honest nothing, but I'd
take a guess that your a clipperhead looking at this, so it's written
100% in CA-Clipper so thats one thing going for it!!

Many people ask if Clipper can be used to write games, well this is
just a small illustration of the fact that you can. It continues my
series of programs and function that make the use of Text Mode
applications that bit more appealing to the user!

As such this has been released into PD, some ideas on the game
structure were pulled from other Tetris games i've seen, lets face it
how many different ways can tetris be written??

Thanks must go to some of the original Clipper Tetris games i've seen,
they at the very least inspired me to take a bash at it myself!!

You will also find enclosed a RANDOM function GT_RAND1(), and an
Array to Disk and Disk to Array functions GT_A2Disk() and GT_Disk2A()
respectively.

So if the tetris game itself doesn't find its way onto a hidden hotkey
in your applications, perhaps the random or array functions might!

Please enjoy the code as much as I did writing it, if you have any
suggestions or comments to make about the code, then please do not
hesitate to moan, grumble or suggest! At the very least if you find
any of the code included herein of any use, please drop me a short
email to keep me informed of what you are using, and how its
benefiting you!

This is the Clipper SOURCE CODE to a variable length field Xmodem
transfer protocol.

Generally, xmodem transfers packets of 128 bytes, but this version
sends a single standard length header, and that header redefines the
length of the rest of the blocks in the transfer. Each packet includes
a CRC check, and the whole thing was created for file transfers from
handheld devices to host computers. (generally, to a PC)

When developing files on a handheld, the file format is usually just a
flat file. This protocol allows these flatfiles to be transferred to
the host a single complete record at a time, where it is generally
transferred into the file file format.

This source requires SilverClip library to compile, but the .EXE is in
there if you want to play with it. It requires a null modem cable
between the two devices.

HotPick() is a general 'picklist' way to select records in a database.
Simply provide a database name and a list of fields to display and
HotPick lets you point to the record you want.

Add index, field header names, row and column positions and you get
elegant control of your 'Pik.'

Written some time ago by Phil Barnett, this modification by Ted
Cleaver changes HotPick's 'engine' from Dbedit to TBrowse.

Returns nReturnValue := RECNO() or 0 if no record selected

Features:

1. HotPick() can work progressively through a database by returning
to the most recent record 'picked'.

2. HotPick() will work without an open index, using only cursor keys
to find a selection. With an index, HotPick() will do a
'progressive' SEEK on ascii CHR(32) through CHR(122).

3. Defaults to self centering browse box, but can be positioned
using optional row and column parameters.

The new menu routine presented here replaces Clipper's standard menu
routine. It only requires that you add an #include line in your
program to use it instead of the standard routine. It has no
incompatibilities with old menu syntax and/or features, as it is
upward compatible both in syntax and runtime features. If the new
features aren't exploited, your program will continue to function
normally. However the new routine extends the syntax of the
abovementioned commands by offering several new optional clauses and
other facilities that will be further examined in detail.

There are a lot of new facilities with the new routine. However, it is
very easy to start using it, as one can learn to use it one feature at
a time. Also, defaults are used for every feature so that you can
achieve maximum ease of use and maximum compatibility with old
standard behaviour.

Letter Merge 3.0

PUBLIC DOMAIN by PHIL BARNETT

This is the third generation of this merge SOURCE CODE.

While version 2 was stable, it wasn't perfect, and it wasn't very
freindly to being inserted in existing products. Also, it printed ALL
matching records in the file.

This new product was modified to make insertion into existing products
a snap. Simply link it in. The only assumptions this code makes is
that you have a table open, and that the correct record is selected.

Letter Merge 3.0 is a letter writing editor which can imbed data from
fields and Hewlett Packard or Epson printer codes right into the text.

The print routine prints only the selected Letter combined with the
fields from the current record.

In many years of using the merge code, I found that most of the time
people wanted form letters that they could print against a single data
record.

Select a record, hotkey to the letter menu, and print a single letter.
Letter Merge 3.0 provides that in a simple and easy to use system.

If you really need a mailmerge, it will be easier to grab the old
version 2 and use it.

In Letter Merge 3.0, Hewlett Packard LJ codes table is an exact
replacement for the older Epson FX codes in the older merge 2 product,
so if you abandoned the old one because your clients used lasers, you
can use it again with the new printer code table from version 3.0. I
renamed the original EPSON table to EPSON.DBF, and the new HP table is
HEWLPACK.DBF. Copy whichever you need to PR_CODES.DBF.

Also, the HP table makes a nice reference for any time you need HP
printer escape codes.

Another facet of Letter Merge 3.0 is that letters created for
different tables are isolated into their own directories, so there is
no possibility of merging a letter with the wrong data structure.

Also removed from the old to the new product were:

1. Headers
2. Footers
3. Lines per page coded to 66

Please feel free to modify this to your own use. If you make
improvements, and they are generic in nature, I'd like a copy to
update the code with.

Well maybe this is just a mild shower or maybe everyone else has seen

I have just implemented this and thought it would be useful to get
additional comments, testing, or ideas. So, following is some code
which intervenes in all of Clippers movement commands and attempts to
verify the results of the index movement against the actual data in
the dbf.

There is certainly some sacrifice in performance as a result of the
intervention. I tested 5928 seeks - performance time requirement
doubled - but we are talking about 1/10 of 1 second. So see what you
think.

Phil,

Here's a version of your structure modifying code which you posted on
comp.lang.clipper. The 3 functions have been telescoped to 1, and a
supervisor routine has been added, allowing 1 backup to be made per
file modified, rather than 1 backup per modification made. This makes
it easier to do a total rollback if any change fails. And the creation
of backups have been placed in a sequence to ensure that the backups
have been made properly before modifications are allowed. Although it
might be seen as a radical revision of your code, it is still
basically your code (I was hard-coding every change, would you
believe), so it's up to you as to what happens to it.

---

And then, as I was drifting off to sleep, I thought about the times
that you actually have to convert the data from one form to another.
DBEVAL, I thought, would be a nice addition to the restructuring
functions. And having tried it, it makes sense -- a field can be
renamed by doing an ADD, a DBEVAL which copies from the old field to
the new field, then a DEL. Not to mention all of the other things
that a block can do. Sure you can do them outside of the restructure,
but allowing them inside means that: 1. as above, you can do a rename,
and 2. that only one set of backup files is needed for the whole of
the process and so a rollback to a clean situation is possible without
devouring acres of diskspace by doing a unique backup between each
modification.

---

And then, as I was thinking about it the next day, I thought that
there were some pretty big files out there. 3 passes of one of those
to rename a field wasn't going to get any thanks. So I re-coded it to
do a 1-pass rename, and closed some files that I had left open.

---

In response to your well-founded criticisms, I re-coded so that the
original files were copied, and all operations took place on the
copies. Then, when all commands had been processed successfully, the
originals were deleted and the copies were renamed to the originals'
names. If 1 command failed, the copies were deleted, and the process
exited.

The speed search routines allow you to search on any word within a
field. It is especially useful on large databases, since the '$'
operator and at() function could be used but becomes unacceptably slow
the larger the database becomes.

Speed search allows multiple fields to be added to the index. So, for
example, if you have 3 address fields and you want to search on any
element in these fields, you can pass all three field names.

An example of the speed search routine, working on a 'real' inventory
database with 11,500 items. The database had a 30 character
description field, which has on average 4-5 words. A search database
containing 46,000 elements was created using space and the / character
as delimiters. The combined speed search element databases and
corresponding indexes took over 1MB of space.

Performing a basic search using a 486SX-25 standalone machine took on
average less than 1/2 seconds using the speed search, and over 10
seconds using the '$' operator.

Multi tasking scheduler State Machine - needs Class(y) and OnTick()

The idea behind this module is, to allow high level procedures and
functions to be execute in the background, no matter what your main
programm is doing. It should be easy to use without modification
to your existing applications.

Since the best result can be achieved when small pieces of code are
executed simultaneously, I'm using only objects for background
execution, calling their methods through the scheduler. I.e.,
thinking of a typical communication over the serial line, you have 4
different states: waiting for data, preparing data to be send, sending
data. (Thats why this is also called a 'state machine'). Each of
these states (at least) can be coded in a simple method of a, say,
serial class. Now you must add a method to select the appropriate
state and your background communication is ready.

This is a PUBLIC DOMAIN Clipper SOURCE CODE replacement for the
Clipper Tools III function showtime().

It also contiains two supplemental functions PUTCLOCK() and
GETCLOCK(). These two functions make it easy to turn the clock on and
off without changing the settings, or even knowing what they are.

For instance, you can set the clock in some obscure section of code,
and later anywhere in your code you can:

putclock() // stops clock but keeps settings
fbrowse( 'xxx.txt' )
getclock() // starts clock with previous settings

It requires the NanForum library FT_ONTICK() function. (PUBLIC DOMAIN)

This is a method of declaring memory variables for your software into
an array, and generate a header file which creates manifest constants
for the field elements of the array.

Benefits:

- local representation of database records
- pure "memory" working
- mixing of databases with same field names
(a_mydata[MYDATA_AGE]:=YOURDATA_AGE[YOURDATA_AGE])
- one variable for whole database record (a_mydata)
- wide space for field names (=symbolic constants like
MYDATA_AGE)
- FULL compiler checking (compiler parameter /es2) for field
names
- modification of SOURCE CODE in second: run STRU2.EXE again,
all sources will be changed (accurately - include files)

TB2Html() generates HTML tables based on TBrowse objects which is
passed as argument (along with target HTML file name and optional
title).

It respects custom skip blocks, so it can be used for converting
arrays as well as standard DBF files.

TB2Html evaluates field data the same way TBrowse do (evaluating the
field code block) so works with calculated columns without any
problems.

It also respects any additional column formatting (TBColumn:picture)
and replace empty values with non-breaking spaces.

Table header is automatically generated from TBColumn:Heading with
support for multi-line headers.

This article has been prompted by some very public begging by David
Peterson. No apologies are offered if the work is detected as being
Summer '87ish. It is. But don't worry, you can rework them and
resubmit them in next month's Clippings!!!

Some years ago I had the craving to work with some heavenly bodies
.... astronomical that is :-^). I needed to calculate the arctangent
of a number associated with some solar radiation data and found that
there was a sad lack of precanned Clipper functions to suit. Whilst
some trig functions had been published, e.g by Straley, they had
limitations on their input ranges or had inherent errors. So I
massaged them and the following code resulted.

Polynomial approximations can be used to achieve many solutions with
quite high orders of accuracy as these examples demonstrate. Have you
improved on someone's code lately? Why not submit it. At least it will
keep David's begging bowl hidden.

USCOPE.PRG is a Universal Scoping routine which should be able to
implement scopes on any RDD using either Clipper 5.x or Xbase++.

USCOPE.PRG uses base language and RDD commands to implement scopes.

Now you can have scoping functions while using generic NDX, NTX, CDX,
MDX, NSX, SIX and COMIX indexes, and use the same function names when
switching between all these RDD's. Probably even ODBC.

(of course, it makes sense to use native scoping commands whenever
possible)

With this library, you can:

somealias->( dbsetorder( n ) )
somealias->( u_setscope( 0, topkey ) )
somealias->( u_setscope( 1, bottomkey ) )
somealias->( u_dbgotop() )

// this loop is now scoped between topkey and bottomkey inclusive
do while somealias->( !u_eof() )
... perform work ...
somealias->( u_dbskip( 1 ) )
enddo

somealias->( u_clrscope( 0 ) )
somealias->( u_clrscope( 1 ) )

Scopes can be alpha, numeric or dates and must match the active index.
You can have multiple scopes set up on multiple aliases and multiple
index orders at the same time. changing alias or index order selects
the scope for that unique combination. No filters are set or used by
these generic scoping functions.

In order for these routines to work, the language/RDD combination must
support:

dbgotop()
dbgobottom()
dbseek()
indexkey()
indexord()
alias()
eof()
bof()
& (macro command)

A group of functions used to seek keywords into data located anywhere
in a key-expression. This works equally well on table data as array
data.

For example, searching for 'gas' might reveal:

2" Gasket
Gas Can, 2.5 Gallon
#2 Form A Gasket

You can also restrict the search to exact matches, so searching for
'gas' from the same data as above but with exact matching turned on
would reveal only:

Gas Can, 2.5 Gallon

This code does not use any locate or $ statements, so it is very fast.

A little present for all you fellow clipperHeads out there in NetLand.

You may do with this code as you will, it comes with but a few
guarantees :-

1. It will occupy some disk space
2. It may occupy some processor time

Beyond that there are absolutely no guarantees at all, but it is

libraries.

How you hook it into your user interfaces is left as an exercise for
the reader. There are more text mode screen savers where this one
